My project is a 4 motor spirograph which makes a single laser light into amazing geometrical shapes. It is easy to do it yourself, you need know something about electronics and soldering.
You need:
If you want to connect an indicator LED, you might want to connect a resistor there, depending on the voltage. At 9 volts I used a 10K resistor.
You can buy these components on ebay or aliexpress. You have to connect the main switch between the power supply and the other switches, and the small switches before the circuit attached as a picture. Any questions, just ask.
